Embodiment 1

[0025] In this embodiment, the ecological board includes a substrate layer and a composite board. The substrate layer includes a core board 1 and an upper middle board 3 and a lower middle board 4 bonded to the core board through a substrate adhesive layer 2. The composite board includes an outer board 6 and a melamine-impregnated paper 7 attached to one side of the outer board 6, the upper middle board 3 and the lower middle board 4 are bonded to the other side of the outer board 6 through the composite board adhesive layer 5 .

[0026] The outer panel 6 is technical wood.

[0027] Because of national standards or customer order requirements, the thickness of the finished ecological board is a definite value. The thickness of the composite board composed of melamine impregnated paper 7 and the outer board 6 remains unchanged, and the thickness of the substrate layer composite is also unchanged. The ecological board of the present invention is placed on the substrate The uppe...

Embodiment 2

[0033] In this embodiment, the similarities with Embodiment 1 will not be repeated, and the difference is:

[0034] In the production process of the ecological board, in the first step, the duration of hot pressing of the core board, the upper middle board 3 and the lower middle board 4 is 25 minutes, the temperature is 130 degrees Celsius, and the pressure is 1.5 MPa.

[0035] The duration of hot pressing of the outer plate 6 and the melamine-impregnated paper 7 is 10 minutes, the temperature is 140 degrees centigrade, and the pressure is 2 MPa. The outer board 6 is poplar.

[0036] In the second step, the temperature of cold pressing is 30 degrees Celsius, the duration is 30 minutes, and the pressure is 1 MPa.

Embodiment 3

[0038] In this embodiment, the similarities with Embodiment 1 will not be repeated, and the difference is:

[0039] In the preparation process of the ecological board, in the first step, the duration of hot pressing of the core board, the upper middle board 3 and the lower middle board 4 is 15 minutes, the temperature is 115 degrees Celsius, and the pressure is 1.0 MPa.

[0040] The duration of hot pressing of the outer plate 6 and the melamine-impregnated paper 7 is 6 minutes, the temperature is 120 degrees centigrade, and the pressure is 1.4 MPa. The outer board 6 is eucalyptus.

[0041] In the second step, the temperature of cold pressing is 20 degrees Celsius, the duration is 20 minutes, and the pressure is 0.6 MPa.

Abstract

The invention discloses an ecological plate. The ecological plate comprises a base plate layer and a composite plate; the base plate layer comprises a core plate, an upper medium plate and a lower medium plate, wherein the upper medium plate and the lower medium plate are respectively adhered on the upper surface and the lower surface through base plate adhesive layers; the composite plate comprises an outer plate, and a piece of melamine impregnated paper which is externally adhered on one of the surfaces of the outer plate; the upper medium plate and the lower medium plate are both adhered to the other surface of the outer plate through the composite plate adhesive layer. A preparation process of the ecological plate comprises the steps of 1, polishing two surfaces of a blank and cutting the edge to obtain the base plate layer; thermally pressing the outer plate and the piece of melamine impregnated paper to obtain the composite plate; 2, performing cold pressing and edge cutting for the base plate layer and the composite plate to obtain the final ecological plate. With the adoption of the preparation process, three wastes with small thickness and degraded and small fuel woods can be used for preparing the base plate layer, so that the resource utilization rate is increased; the process and time can be decreased, and the probability of reject ratio is reduced; the energy consumption in the production process can be decreased.

Description

technical field [0001] The invention relates to the field of decorative boards and processing, in particular to an ecological board and a preparation process thereof. Background technique [0002] Ecological board is a common name for wood-based panels with impregnated film paper veneer. Compared with traditional stickers, it has the advantages of high temperature resistance, acid and alkali resistance, moisture resistance, fire prevention, etc., and combines the functions of stickers and plywood into one, saving Decoration costs and labor costs are widely used in interior decoration. The ecological board in the prior art is obtained by processing fine wood boards as raw materials. Wood is an important production and living resource for human beings, and it is also a scarce resource. The annual wood gap in my country reaches 100-150 million cubic meters, and the annual wood production and A large number of "three leftovers" and "sub-small fuelwood" produced during the proc...
